Igor, I am now trying to write something like in your book, but first of all
I don't want to define blocks in one tml page, and a number or blocks in
java-class. I try to get component instance dynamically using method
componentSource.getComponent(String)
but I have an exception on this method.
org.apache.tapestry5.internal.services.RenderQueueException
Render queue error in BeginRender[Step:dynamicformfield.delegate]: Failure
reading parameter 'to' of component Step:dynamicformfield.delegate: Unable
to resolve 'textfield' to a known page name. Available page names: (blank),
About, Contact, ExceptionReport, Index, PropertyDisplayBlocks,
PropertyEditBlocks, ServiceStatus, Step.
I can't understand why Tapestry looks for pages and not components. So for
example if I change method to componentSource.getPage("About"); everything
renders fine - I get a number of About pages rendered inside my form. (About
is one of pages defined in my application)
